Some of you may remember my thread on oil consumption. It's more complicated and i'm starting a new one now.

In short, my son drives 03 Ion and lives in another town and visits us about once a month. i checked oil a month ago and it looked like it was very low (barely on the dipstick) and it took ~2 qts to fill it up. I sort of yelled at him and he claimed oil was fine before the trip. I thought he lied about checking. He went back and I asked him to check oil again. He said overfilled. I assumed he does it wrong. So, I checked this weekend and it looks overfilled alright, at least 1qt, maybe more. Maybe it's not burning oil like I though, but somehow oil was trapped in upper part of crankcase when I checked before?

150,000+ miles. I like to check on cold engine after sitting overnight. My driveway is not perfectly flat, but not hilly either.
